Social Security full retirement age for 1958
Federal law ties full retirement age to the year you reach 62. For people born in 1958 it is 66 and 8 months, which you reached in 2024 if you were born January–April, or 2025 if you were born May–December. Claiming at 62, in 2020, permanently reduces the monthly benefit; waiting past full retirement age increases it. Social Security considers you to reach an age on the day before your birthday, so if you were born on January 1, 1958, you are treated as born in 1957 and your full retirement age is 66 and 6 months.
